Card Edge Connector
Industrial, IT Datacom
When you're designing a DDR5 memory interface into a space-constrained product — a laptop, an industrial controller, a networking blade — the connector is rarely the first component you evaluate. But it's often the one that causes the most late-stage problems. Board real estate is tight. Z-height budgets are measured in fractions of a millimeter. And DDR5's higher data rates mean every signal path through the connector matters more than it did on DDR4.
This 262-position, 9.2mm standard-height connector is built for exactly those situations. It pairs the DDR5 SO-DIMM form factor with a vertical profile that fits the majority of compact module designs, giving you a production-ready interconnect without forcing compromises on your PCB layout.
The 9.2mm standard height occupies a practical middle ground for module designers. It's tall enough to provide adequate clearance above the PCB surface — important for airflow and mechanical retention — yet compact enough to fit within the enclosure budgets of portable and embedded products. If your chassis can't accommodate a full-height UDIMM socket, this profile gives you DDR5 capability in a footprint that actually fits your mechanical stack-up.
DDR5 pushes data rates well beyond what DDR4 required, and the connector is part of the signal path — not just a passive mechanical interface. The contact geometry here is designed to minimize stub effects and crosstalk between adjacent pin positions. That means cleaner signal margins when you're running at the upper end of DDR5 speed bins, which matters whether you're qualifying for JEDEC-standard operation or validating higher-performance modules.
Not every DDR5 SO-DIMM connector suits every design. The table below maps common decision factors to connector characteristics so you can narrow your selection quickly:
Design Factor | This Connector (9.2H STD) | Low-Profile Variant | Reinforced Variant |
|---|---|---|---|
Z-height | 9.2mm standard | ~5mm or lower | 9.2mm+ with modified contacts |
Target application | Laptops, SFF PCs, embedded | Ultra-thin tablets, 2-in-1s | Vibration-heavy industrial |
Module retention | Standard friction fit | Standard or snap-in | Enhanced retention |
Thermal headroom | Moderate clearance | Limited | Higher airflow required |
The 262-pin layout follows the DDR5 SO-DIMM standard, which adds more power and ground pins compared to DDR4's 260-pin SO-DIMM. Those extra pins aren't arbitrary — they support DDR5's on-module power management IC and the split-rail voltage architecture. If you're migrating from a DDR4 design, the power delivery section of the connector carries different current characteristics. Your PCB power plane design needs to account for that, or you'll see voltage droop under peak load that wasn't present on the previous platform.
This connector uses surface-mount termination. SMT is the right call for most volume-production scenarios — it's compatible with standard reflow profiles, reduces assembly complexity, and keeps per-board cost lower than press-fit alternatives. Press-fit connectors have their place, typically in applications where reflow compatibility with adjacent board components is a concern, but for the majority of compact DDR5 designs, SMT is the practical and economical default.
Laptops, mini-PCs, and portable workstations are the most natural fit. The standard height works within typical laptop enclosure stacks, and the SMT pads integrate cleanly into high-volume PCB assembly lines without requiring special handling.
Industrial controllers, HMI panels, and compact PLCs increasingly adopt DDR5 as processor platforms evolve. The connector's contact design holds up well under the thermal cycling these environments impose — repeated heating and cooling cycles that can fatigue lesser contacts over time, leading to intermittent memory errors that are notoriously difficult to diagnose in the field.
Edge routers, SD-WAN appliances, and small-form-factor network switches benefit from the DDR5 bandwidth uplift while keeping board area minimal. The SO-DIMM form factor lets you offer memory configurability — different SKUs with different memory capacities — without dedicating a large PCB region to soldered-down memory chips.
Every CONSHARE connector ships within tightly controlled dimensional tolerances — linear dimensions held to ±0.15mm at three-decimal precision, angular features to ±1°. That precision isn't just about meeting a spec on paper. It directly affects how consistently the connector seats on your PCB during pick-and-place, and how reliably the memory module seats in the connector after repeated insertion cycles. Poor tolerance control is one of the most common root causes of field returns in memory connectors, and it's the first thing we eliminate at the production stage.
Standard configurations ship from production inventory with typical lead times of 2–4 weeks for volume orders. For projects with specific requirements — customized packaging, modified contact plating, or customer-specific qualification testing — CONSHARE supports tailored production runs with engineering review. We work with your hardware team to define acceptance criteria before production begins, so what arrives at your facility matches what your design expects.
Each production lot goes through:
Automated optical inspection on 100% of units for solder pad geometry and contact alignment
Electrical continuity testing on a sample basis per lot
Insertion/extraction cycle validation to confirm mechanical durability meets rated cycle life
Dimensional sampling per AQL standard to verify tolerance compliance
No. DDR5 SO-DIMM uses a 262-pin configuration with a different keying notch position compared to DDR4's 260-pin SO-DIMM. The connectors are physically not interchangeable — this is intentional, to prevent incorrect module installation during assembly or field upgrades.
The connector is designed to support the full range of DDR5 SO-DIMM data rates defined by the JEDEC standard. Actual achievable speeds depend on your module specification, PCB routing quality, and system-level signal integrity validation.
The standard configuration suits commercial and industrial temperature ranges. For automotive-grade applications with extended temperature or vibration requirements, contact CONSHARE to discuss a qualified variant with appropriate testing and documentation.
Standard tape-and-reel packaging is available, configured for compatibility with mainstream pick-and-place equipment. Tray packaging can be arranged for specific production setups on request — just let us know your equipment model during the quoting stage.
Yes. CONSHARE provides mechanical drawings, recommended PCB footprints, and reflow profiles. For complex designs, our engineering team can review your layout and provide recommendations before you commit to tooling.
